Gamma Knife Surgery

Gamma Knife surgery (GKS) is a non-invasive, advanced form of radiosurgery used to treat brain tumors and other neurological conditions. Unlike traditional surgery, it does not involve incisions but instead uses highly focused gamma rays to target abnormal tissues with extreme precision.

Developed in 1968, Gamma Knife has become a gold standard for treating complex brain disorders while minimizing damage to surrounding healthy tissue.

What Does Gamma Knife Surgery Treat?

Gamma Knife surgery is primarily used to treat:

• Brain tumors (benign and malignant)

• Arteriovenous malformations (AVMs)

• Trigeminal neuralgia

• Acoustic neuromas

• Pituitary tumors

• Parkinson’s disease (for certain symptoms)

• Epilepsy (in select cases)

It is especially beneficial for deep-seated or hard-to-reach tumors where conventional surgery poses high risks.

Frame vs. Frameless Gamma Knife: What’s the Difference?

Traditional Frame-Based Gamma Knife

• Uses a rigid metal frame attached to the skull for stability.

• Ensures sub-millimeter accuracy.

• Requires local anesthesia for frame placement.

• Best for small, well-defined targets.

Frameless Gamma Knife (Mask-Based)

• Uses a custom thermoplastic mask instead of a frame.

• More comfortable for the patient.

• Suitable for larger or multiple treatment areas.

• May require multiple sessions compared to frame-based.

The choice depends on the patient’s condition and tumor location.

What Happens During Gamma Knife Surgery?

1. Preparation – The patient may undergo MRI or CT scans for precise targeting.

2. Head Frame or Mask Placement – For frame-based, a lightweight frame is fixed to the skull. For frameless, a mask is molded.

3. Imaging & Planning – Doctors use 3D imaging to map the treatment area.

4. Treatment Delivery – The patient lies on a bed while the Gamma Knife machine delivers radiation beams.

5. Completion – The session lasts 30 minutes to a few hours, and the patient can usually go home the same day.

Benefits of Gamma Knife Surgery

• Non-invasive – No incisions or scarring.

• High precision – Targets only abnormal tissue.

• Minimal side effects – Lower risk of infection or complications.

• Quick recovery – Most patients resume normal activities within days.

• Effective for inoperable tumors – Treats lesions deep in the brain.

Risks and Complications of Gamma Knife Surgery

While generally safe, potential risks include:

• Swelling or headaches (usually temporary)

• Nausea or dizziness

• Radiation-induced tissue changes (rare)

• Hair loss near the treatment area

• Seizures (in very rare cases)

Most side effects are mild and resolve within weeks.

Gamma Knife Procedure Step-by-Step

1. Consultation – The neurosurgeon evaluates if Gamma Knife is suitable.

2. Pre-treatment Imaging – MRI/CT scans are done for planning.

3. Head Stabilization – Frame or mask is applied.

4. Radiation Delivery – The machine administers focused beams.

5. Post-Treatment Monitoring – Brief observation before discharge.

Recovery After Gamma Knife Surgery

• Same-day discharge in most cases.

• Rest for 24-48 hours is recommended.

• Follow-up scans to monitor progress.

• Gradual symptom improvement over weeks/months.

Most patients return to work within a few days.
